Abstract
A gasket comprises an annular gasket portion arranged to enclose a port hole of a heat exchanger plate. An inner edge of the gasket portion defines an area including a reference point coinciding with a center point of a biggest imaginary circle fittable within the area. The area has a form defined by a number of corner points of an imaginary plane geometric figure of which at least one is displaced from an arc of the circle, and the same number of thoroughly curved lines connecting the corner points, wherein a first corner point is a first distance from the reference point, a second one is closest to the first corner point in a clockwise direction and on a second distance from the reference point, and a third one is closest to the first corner point in a counter clockwise direction and on a third distance from the reference point.
